Saudi Arabia dismisses UN report criticising its role in the Yemen war, says its figures are inaccurate and misleading'.

Riyadh has rejected a United Nations report that placed a Saudi Arabia-led military coalition to a blacklist of child rights violators for causing the deaths and injuries of hundreds of children in war-torn Yemen.

According to UN figures released on Thursday, the alliance was responsible for killing and maiming 683 children in 2016, and for 38 verified attacks on schools and hospitals during the same period.

In response, Saudi Arabia's UN envoy said on Friday that the information in the world body's annual report on children in armed conflict was "inaccurate and misleading".

"We exercise the maximum degree of care and precaution to avoid civilian harm," said Abdallah al-Mouallimi.

A Saudi-led military coalition was formed in March 2015 to support Yemen's internationally recognised government in fighting Houthi rebels.

The conflict has killed more than 10,000 people and has injured more than 40,000 to date, according to the UN.
